I think the one thing I hate most about depression is the lack of energy. There just seems like there is no back-up energy for anything. Things are going fine and then something comes up and everything comes tumbling down. Usually it is totally unexpected.
Last night, the spectre of depression hit both Nick and I. It was not a whole lot of fun. We started to pack and it just knocked me. Like I said, it is usually unexpected and then it saps all my energy.
